Hidden achievements

The 14 achievements Steam does not list are tied to story progress. According to the 1.0 endings breakdown at wikily.gg they include one for each of the 3 endings, one for an ending with each of the 3 characters, one for any ending within 3 hours, one for the escape without killing a guard, one for dying and one for dying on layer 6 or deeper. The remaining few are not documented yet. Details are in the endings guide behind spoiler folds. Database

Hunting tips

  • Do the sandbox-only experiments (console) in the tutorial sandbox so your real run keeps achievements.
  • Stack easy ones on layer 1: Lightfooted, Reading Comprehension and Not a Care in the World.
  • Paradise has infinite last stands, which makes risky ones like Dead Man Walking safer to attempt.
